Hi,

The sudo apt update command failed because one of your configured package repositories does not support the Debian “trixie” release.
The specific error, “404 Not Found,” indicates that the requested Release file is missing from the server at that specific URL and for that specific version.

->> how to fix the error:
Identify the problematic repository.
The error message points to a repository with the URL structure Index of linux/ubuntu/ trixie. This is likely an external repository (PPA or similar) that has not been updated for the current Debian Trixie release.

->> Fix the issue
You can either remove the problematic repository entry or, if a compatible version exists, change the codename in the configuration file to a supported parent release (like ‘bookworm’ for Debian Trixie, or the Ubuntu equivalent for that repo). The safest and most common solution is to remove the problematic source:

***Locate the source file:
Use grep to find which file contains the problematic line in bash:

grep -r “Index of linux/ubuntu/” /etc/apt/sources.list*

***Edit the source file:
Once you identify the file (e.g., in
/etc/apt/sources.list.d/some-package.list or /etc/apt/sources.list), open it with a text editor /nano or antoher/ as a super user - command in bash:

sudo nano /etc/apt/sources.list.d/some-package.list

*** Remove or comment out the line:
Delete the line causing the error or add a # at the beginning of the line to comment it out.

*** Update your package lists:
After saving the changes, run the update command again in bash:
sudo apt update

The error should no longer appear, and your system will update from the remaining, valid repositories.

PS.
Lass mich wissen, ob dir das bei der Aktualisierung des Gesamtsystems geholfen hat.

Unfortunately, I’m having trouble implementing this correctly because I don’t really understand how to do it yet.
How do I find the right line?
Is it the line where the error is displayed?

It would help if you said where you got those repo definitions from.

In debian-12 you are using a repo for debian stable - generally a bad
idea to mix versions.

In the docker case, you are mixing ubuntu and debian repositories -
rarely a good thing to do. But in this case you are using ubuntu but
specifying trixie, which is a debian version.
Change this line:
https://download.docker.com/linux/ubuntu trixie Release
to
https://download.docker.com/linux/debian trixie Release

I never presume to speak for the Qubes team. When I comment in the Forum I speak for myself.

How can this file be saved or changed?

Trixie, a Debian version, is specified.

Change this line:

Index of linux/ubuntu/ trixie Release

To

Index of linux/debian/ trixie Release
